I got this from another site that I visit but it's really fun.
In a dark dysmal hallway there sits a lone blinking light. As you come up to it it says cola on the side. However, when you put a dollar and two quarters into it, it gives you a dead president and two quarterbacks instead of a coke.
In fine print it tells that it's the "Disfunctional Vending Machine: caution, anything put into the machine comes back defective! Use at own risk"
How the game works is that someone will put something into the machine... and the next person posts what the other person recieves. Then that person posts about what they put in the machine.
Very much like the wish defect only this time it's a vending machine and there for is improbably funny trying to imagine said items coming out of the slot.
I put in Hillary Clinton, some matches, a can of gasoline, and my snotty tissue.
